1 UNIT 5 AGRICULTURAL GEOGRAPHY

2 World Land Area for Agriculture
27% too cold 27% too dry 36% too mountainous 2% too swampy 8% juuuuuuust right! To feed over 7 BILLION PEOPLE!!!!!!!!!!!!!!

3 Brief History of Agriculture
Hunter-Gatherers Move where food is Most of human history up to 14,000 years ago Impact Low population growth Most activities center around acquisition of food-no time for other pursuits.

4 Brief History of Agriculture
1st Agricultural Revolution (aka Neolithic Revolution) Domestication of plants & animals Fertile Crescent 14,000 years ago Impact More reliable food source Sedentary lifestyle Specialization led to social stratification Larger population Birth of civilization

5

6 Brief History of Agriculture
2nd Agricultural Revolution Improved methods of cultivating, harvesting, storing and transportation of agricultural products 17th century –mid 20th century Europe/US Early years-enclosing farms, bigger farms, better soil preparation (crop rotation) Later years-mechanization (w/Industrial Revolution), better fertilizers & pesticides, refrigeration & transportation Impact More food and more choices Less farmers needed (go to work in factories) More urbanization

7 Brief History of Agriculture
3rd Agricultural Revolution (aka Green Revolution) Using biotechnology and Genetically Modified Organisms to expand crop yields. Mid 20th century –present in US, Mexico, India, SE Asia Impact Higher yields (more food) Less famines Criticisms Potential for super bugs & super diseases/reduced diversity Increased water & energy use and pollution Inability for small farmers to utilize technology

8 Brain Drain Activity: Create an illustrated timeline covering the 3 Agricultural Revolutions. Make sure to include at least 2 events for each era and the greater impact. Use the paper provided You have 25 minutes to complete.

9 QW /5 & 6 Look over the concepts we discussed last class (Agricultural Revolutions) “Tweet” a response on the back of your ESPN chart describing what LEVEL on the scale you are pertaining to those concepts and why. You only have 140 characters! Be CAREFUL!

10 Agricultural Methods Do all farmers utilize the same methods around the world? Why not? What factors determine what is grown where and how? Environment (soil, climate, etc.) Culture Economics EXAMPLES???

11 Agricultural Methods Labor Intensive CAPITAL INTENSIVE
Large amount of people/little amount of capital Many people using simple tools & methods Human labor used in almost every step Small amount of people/large use of capital Single farmer produces as much as 100 labor-intensive farmers through use of capital Nearly every step automated

12 Agricultural Methods Labor Intensive vs. Capital Intensive
Use depends on price of labor & capital in a region As regions develop economically, agriculture shifts from labor to capital intensive

13 Agricultural Methods Intensive (land use) Extensive (land use)
Large amount of output per acre Due to concentrated use of labor and/or capital Smaller output per acre Labor and/or capital spread out over a large area of land

14 Agricultural Methods Intensive vs. Extensive (Land Use)
Dependant on price of land and population density Separate from labor/capital intensive spectrum Intensive can be capital intensive (greenhouses, feedlots) or labor intensive (rice paddies) Extensive can be capital intensive (US wheat farmer)or labor intensive (Nomadic herders)

15 Agricultural Methods sedentary nomadic Work & live in single location
Types Tenant farmers/sharecroppers Family farms Corporate farms Systematic pattern of movement based on proven locations NOT random wandering Types Horizontal-one water source to another Vertical-lowlands in winter highlands in summer (transhumance) Shifting cultivation (a.k.a. slash & burn)-burn overgrowth for nutrients, stay a few years, move on, return years later

16 Agricultural Methods Sedentary vs. Nomadic
Depends on physical geography & cultural traditions

17 Agricultural Methods irrigated Non-irrigated
Watering crops by means other than rainfall Wells, tunnels, trenches, spraying, drip systems, dams/canals, etc. Watering crops only with rain fall

18 Agricultural Methods Irrigated vs. Non-irrigated
Irrigated necessary for large scale commercial agriculture & areas with uncertain rainfall Non-irrigated only exists in areas with reliable rainfall and very poor subsistence areas

19 Agricultural Methods subsistence commercial
Just enough to feed families/self-sufficient farming villages Sell output for cash Pure form corporate “factory farms”

20 Agricultural Methods Subsistence vs. Commercial
Most farms worldwide exist somewhere on a spectrum between both. Except factory farms. Shift from subsistence occurs when a region increases in wealth, trade, & specialization Sometimes forced to switch due to political factors (colonialism or communism)

21 Agricultural Methods:
Brain Drain! Guess What I Grow! You and your partner are farmers. Describe your life and the type of farm you work on. Use the terms below to explain the type of farm you work on and what you produce. Try to have your partner guess what you produce and where! Agricultural Methods: Labor Intensive VS Capital Intensive Intensive (Land Use) VS Extensive (Land Use) Irrigated VS Non-Irrigated Subsistence VS Commercial Sedentary VS Nomadic

22 Commercial Agriculture
Organizational Types of Commercial Agriculture Based on land ownership Family farming- small, self-sufficient family owned enterprise. Exists mostly in North America in shrinking numbers Tenant farming- rent land. Produce to feed self and pay rent. Most of the world Sharecropping-pay rent with “share” of the crop. Both parties “share” risk, but can end up tied to the land. Plantations-instituted during colonialism. Used in tropical areas producing tropical crops for export. Now often run by corporations. Collectives-state-owned farms in communist countries producing for the state Garden plots- small areas for collective workers to produce for individual profit (often more productive than collective) Agribusiness-industrialized corporate agriculture.

23 Commercial Agriculture
Agribusiness Organized network from seed to distribution The “industrialization” of agriculture Small number of corporations controlling food source Gaining more prominence and power through globalization More focus on “value added” food products (Processed foods) Examples: ConAgra, Archer Daniels Midland, Smithfield Foods, etc.

24 Commercial Agriculture
Positives of Agribusiness Negatives of agribusiness Efficient in connecting farmers with production and exchange Concentration of agriculture activities Higher yields Greater availability for consumer More choices for consumer Lower prices for consumer Destruction of family farm and farming communities Animal cruelty Questionable health risks through use of antibiotics and artificial hormones Greater pollution Increased energy uses

25 Pros & Cons of Agribusiness
The Meatrix

26 L3: Brain Drain Create a pamphlet comparing 3 types of commercial farms. Include: What you produce and for who Positives Negatives

27 Classifying Agricultural Regions
Subsistence Agriculture Shifting Cultivation Pastoral Nomadism Intensive Subsistence Agriculture Commercial Agriculture Mixed Crop and Livestock Farming Dairy Farming Grain Farming Livestock Ranching Mediterranean Agriculture Commercial gardening & fruit farming Plantation Farming

28

29 Shifting Cultivation Vegetation “slashed”then burned. Soil fertile for 2-3 years, then people move on. Where: tropical rainforests. Amazon, Central and West Africa, Southeast Asia Crops: upland rice (S.E. Asia), maize and manioc (S. America), millet and sorghum (Africa)‏ Declining at hands of ranching and logging.

30 Pastoral Nomadism Breeding & herding of domesticated animals for subsistence. Where: arid and semi-arid areas of N. Africa, Middle East, Central Asia Animals: Camel, Goats, Sheep, Cattle Many nomads are being pressured into sedentary life as land is used for agriculture or mining. Bedouin Shepherd Somali Nomad and Tent

31 Intensive Subsistence Agriculture
Very labor intensive production of rice Where: S.E. Asia, E. India, S.E. China. Grown on flat, or terraced land Double cropping used in warm winter areas of S. China and Taiwan The Fields of Bali Thai Rice Farmers

32 Mixed Crop and Livestock Farming
Crops grown fed to livestock Where: Upper midwest US; much of Europe from France to Russia Crops: corn (most common), soybeans Highly inefficient use of natural resources Pounds of grain to make 1 lb. beef: 10 Gallons of water to make 1 1b wheat: 25 Gallons of water to make 1 1b. beef: 2500

33 Dairy Farming Commercial production of cow’s milk
Where: near urban areas in NA & Europe - Over 90% of cow’s milk is produced in developed countries. Value is added as cheese, yogurt, etc. Dairy Farm, Wisconsin

34 Grain Farming Where: worldwide, but U.S. and Russia predominant
Crops: wheat winter wheat: Southern Great Plains (Kansas, Colorado, Oklahoma) spring wheat: Northern Great Plains (Dakotas, Montana, southern Canada) Highly mechanized.

35

36 Livestock Ranching Where: arid or semi-arid areas of western U.S., Argentina & Brazil, Spain & Portugal. Historically on open range, now sedentary with barbed wire & transportation changes. Environmental effects: 1) overgrazing has damaged much of the world’s arid grasslands (< 1% of U.S. remain!)‏ 2) destruction of the rainforest in Brazil motivated by desire for cattle ranches

37 Mediterranean Agriculture
Where: areas with Mediterranean climate. Surrounding the Mediterranean Sea, California, Oregon, Chile, South Africa, parts of Australia Highly valuable crops: olives, grapes, nuts, fruits and vegetables; winter wheat

38 Commercial Gardening and Fruit Farming
Where: U.S. Southeast, New England, near cities around the world crops: high profit vegetables and fruits apples, asparagus, cherries, lettuce, tomatoes, etc. Truck farming-mechanized and near and for processors Suitcase farming- for produce and near market Both utilize immigrant (sometimes illegal) labor

39 Plantation Farming Large scale mono-cropping of profitable tropical products for sale mostly in US & Europe. where: tropical lowland periphery countries. crops: cotton, sugar cane, coffee, rubber, cocoa, bananas, tea, coconuts, palm oil.

40 Brain Drain Use the 2 world maps to identify where Subsistence Farming and Commercial Farming take place. Commercial Farming: Mixed Crop and Livestock Farming Dairy Farming Grain Farming Livestock Ranching Mediterranean Agriculture Commercial Gardening & Fruit Farming Plantation Farming Subsistence Farming: Shifting Cultivation Pastoral Nomadism Intensive Subsistence Agriculture

44 Quick Write 10/22 On notebook paper create a simple chart with a list of everything you ate yesterday in one column and the ingredients in the other. Do the best you can with the ingredients. Meals for the past 24 Hrs. Ingredients

45 Von Thunen’s Model of Farming Distribution
Examines spatial distribution of farming Crops change without a noticeable change in soil or terrain Based on assumptions Flat terrain No barriers to transportation Argues that transportation to market influences how land is used Climate, soil, methods, technology, & economic state of market also play a role.

46 Von Thunen’s Model of Farming Distribution
4 concentric rings 1st ring-nearest to town-perishables & high priced items 2nd ring-forest for fuel and building materials 3rd ring-less perishable items such as grains 4th ring-ranching & livestock

47 Brain Drain Simulation: Von Thunen Model
Define Von Thunen’s Model. How has globalization altered Von Thunen’s Model? In what ways does the theory pretty much ring true?

48 Settlement Patterns Cadastral systems-method of land survey through which landownership and property lines are defined. Township and Range System-(rectangular survey system) is based on a grid system that creates 1 square mile sections. Metes and Bounds Survey-uses natural features to demarcate irregular parcels of land. Longlot Survey System -divides land into narrow parcels stretching back from rivers, roads, or canals. Primogeniture- system where land is passed down to eldest son. Large landowners dominate.

49 Settlement Patterns Township and Range – The cultural landscape of Garden City, Iowa reflects the Township and Range system. Townships are 6x6 miles and section lines are every 1 mile.

50 Settlement Patterns Metes and Bounds-"Beginning at a stone on the Bank of Doe River, at a point where the highway from A. to B. crosses said river (see point marked C. on Diagram 1); thence 40 degrees North of West 100 rods to a large stump; then 10 degrees North of West 90 rods; thence 15 degrees West of North 80 rods to an oak tree (see Witness Tree on Diagram 1); then due East 150 rods to the highway; thence following the course of the highway 50 rods due North; then 5 degrees North of East 90 rods; thence 45 degrees of South 60 rods; thence 10 degrees North of East 200 rods to the Doe River; thence following the course of the river Southwesterly to the place of beginning."   This, which is a very simple and moderate description by "Metes and Bounds," would leave the boundaries of the farm as shown in Diagram 1.

51 Settlement Patterns Longlot Survey System – The cultural landscape of Burgandy, France reflects the Longlot Survey system, as land is divided into long, narrow parcels. People live in nucleated villages and land ownership is highly fragmented.

52 Settlement Patterns

53 Settlement Patterns

54 Settlement Patterns Cultural Landscape impacted by agriculture.
Developed world-buildings different for different purposes (more functional differentiation) Developing world-more multi-use buildings

55 QW 10/27 Create an ESPEn chart about the image on a piece of paper.
Economic, Social, Political, Human ENvironment Economic Social Political Human Environment

56 Brain Drain Give me the GIST of what we just covered.
You have 20 words to summarize Settlement Patterns (Complete ON YOUR OWN!!) We will share with the class in 10 minutes.

57 Global Agriculture Trends Globalization & Agriculture

59 Global Agriculture Trends
Production

60 Global Agriculture Trends

61 Global Agriculture Trends
Farm Subsidies in developed countries. Farmers paid by their governments to make up difference in what is profitable and what market price provides. Subsidies to the world’s richest farmers directly damage the agricultural economies of the poorest counties. Poor farmers with no help can’t compete with rich farmers that get help.

71 Green Revolution Gains in yields made by…
Higher yielding varieties created by cross breeding. Dwarf varieties: plants are bred to allocate more of their photosynthetic output to grain and less to vegetative parts. Enables planting in closer rows, increasing yields. Bred to be less sensitive to day length, thus enabling double-cropping Very sensitive to inputs of fertilizer and water.

72 Green Revolution Drawbacks… Heavy Use of Pesticides and Fertilizer
Reduced Genetic Diversity = Increased Blight Vulnerability Questionable Overall Sustainability (Heavy use of fresh water and energy) High Dependence on Technology and Machinery Provided/Sold by Core Countries Poor farmers limited access

73 Brain Drain AP Human Geography FRQs – Agricultural & Rural 2001 (1) A. (i) Define the term “Green Revolution” as used from 1945 to the present. (ii) Explain TWO principal agricultural practices/technologies associated with the green revolution. (iii) Name TWO regions, in different parts of the world, where the green revolution has had a significant impact on crop yields. B. Identify and discuss TWO social, political, or cultural conditions necessary for the success of the agricultural practices/technologies of the green revolution. C. Identify and discuss TWO significant economic or ecological factors that may limit the long-term success of the agricultural practices/technologies of the green revolution.
